Hi, i have a 2001 gs300. my ecl came on and the code read 0161 bank2 sensor2 for o2 sensor. it's the rear cylinder (456) post cat. has anyone ever changed their bank2 sensor2 o2 sensor before? becuase some lexus like the ls400 has the o2 sensor connector inside the cabin. is that true for gs300? if so, anything i need to watch out for before making a big hole under my car?
